Microwave imaging of multiple conducting cylinders using local shape functions

A novel technique is presented for microwave imaging of multiple conducting cylinders using local shape functions. In this method, a scattering volume is divided into small sub-scattering regions and assigned a local shape function amplitude. The reconstructed image is represented by the set of local shape functions that satisfy multiple scattering boundary conditions. Monochromatic image reconstructions have a resolution scale of 0.1 lambda for single scatterers; multiple scatterers can be resolved at a separation of 0.42 lambda .>
